Length function

[Mike Palandri]

 A couple potential pitfalls of the SIZE function:

Without combining it with TRUNC, it returns the full size of the item.

When comparing the value returned from SIZE with a literal, the literal must be on the left of the "=", at least on the versions and platforms I've worked with:

This is OK:
if 0 < size(trunc(xxx))

this isn't: 

if size(trunc(xx)) > 0
